Noting the importance of choosing a project that is interesting or relevant to one's personal goals, this manual provides activities which can be undertaken to earn cadette and senior level girl scout interest patches. Part 1 of the manual deals with procedures to develop an interest project, including working with consultants, interviewing, role-playing, and the relationship between interest projects and the Girl Scout Silver and Gold Awards. Interest Projects are grouped in five areas: (1) life skills, including car maintenance, child care, conflict resolution, home improvement, leadership, and developing a business; (2) nature, science, and health, including birds, cooking, inventions, pets, math, space exploration, and women's health; (3) communications, including computers, desktop publishing, media, public relations, reading, and writing; (4) the arts and history, including architecture and environmental design, folk arts, dance, museum, and textile arts; and (4) sports and recreation, including backpacking, camping, outdoor survival, and sailing. Each interest project contains four types of activities, skill builders, technology-related activities, service projects, and career exploration. Details regarding requirements for the interest patch are provided. Included are charts for recording progress and lists of resources and organizations. (KB)
